Lens Problems That I'm Sure Other People Need Help With...maybe.

The other day I found a minolta SRT200 with three lenses for $30; MC ROKKOR-X PF 1:2 f=50mm, AUTO Vivitar TELE-ZOOM 75-260mm 1:4.5, and Quantaray MC AUTO 1:2.8 f=24mm 52ø are the lenses it came with...

The camera I use is the Sony Alpha 100.

By now I assume everyone who is reading knows where I'm going with this; I want to be able to use the lenses with the Sony.

Now my question is can any one help me? Are there any mounts I can purchase online? or is it hopeless?

If it is indeed completely hopeless, where can I buy a new battery for the minolta SRT200?

Thank you all who took the time to read this, I hope you guys can help me and anyone else who is trying to find this information on the internet.
